Description
The utility model relates to a kind of servomotor, particularly a kind of brushless, permanently servomotor.
At present, the servomotor kind mainly contains DC brush servomotor, alternating current asynchronous type servomotor, AC permanent-magnet is brushless synchronized model servomotor etc.In high performance servo-control system, vector control and digital Control Technology are extensively adopted in the control of servomotor, driving.Owing to be servo closed-loop control, existing servomotor adopts coaxial mounted photoelectric encoder to finish the sensing detection of motor turned position and angular speed, angular acceleration.And photoelectric encoder is afraid of oil, is afraid of dust, shock-sensitive moving and impact, and poor reliability, mechanical installation requirement height, difficult in maintenance, useful life is short; Again because photoelectric encoder band commutation signal, so it can't be general between the motor of different magnetic poles logarithm, more can not exchange, and the price height brings many inconveniences to the user in addition.
The end cap of existing servomotor is identical with the housing sectional dimension, and a kind of motor of model can only be connected with certain fixing equipment, can't be connected with miscellaneous equipment in other occasion, and range of application is very limited.
In addition, the bearing of existing servomotor front and rear cover is single shaft and holds, and normal because oil starvation heating or transducing signal is out of control damages in running up is lacked motor useful life, causes heavy losses.
The purpose of this utility model is, overcomes the shortcoming of above-mentioned prior art, and a kind of energy-efficient, long-life, non-maintaining, multimodal brushless, permanently servomotor are provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of long-life multi-mode brushless, permanently servomotor, its composition comprises housing, before, rear end cap, by iron core, winding is formed and is fixed on stator armature in the housing, main shaft, before, rear bearing, by rare-earth permanent magnet, protective sleeve is formed and is contained in rotor on the main shaft, and position of magnetic pole and speed sensing device, it is characterized in that: (1), sensing device is the coaxial mounted contactless change transmitter that revolves, this revolves the change transmitter and has casing, stator, rotor and holding wire, its casing is fixedlyed connected with the servomotor rear end cap, stator is equipped with in the casing inboard, and its rotor is contained on the electric machine main shaft, and its holding wire is drawn the outlet box that is connected on the electric machine casing by casing; (2), front end housing is step, fixedly connected by two flanges with electric machine casing.
The utility model brushless, permanently servomotor, owing to adopt the contactless change transmitter (abbreviation resolver) that revolves to make transducer, substitute mechanical commutation with electronic commutation, realize magnetic vector control and breakdown torque control easily, shock-resistant, vibration resistance is not afraid of dust, can work under adverse circumstances, safe and reliable, long service life, non-maintaining, energy-efficient; Because revolving change transmitter stator can freely adjust at the relative angle of circumferencial direction, it sends signal phase and can regulate consistent with the electromotive force phase place of motor stator winding, therefore the permanent magnet synchronous motor that becomes the various modes that transmitter can be different with the magnetic pole logarithm that revolves of same specification is complementary, the pole pair that is permanent magnet motor can be a pair of, two pairs, three pairs, four pairs or the like, unrestricted, the user selects easy to use.Again because front end housing is step, its sectional dimension can be inequality with electric machine casing, same stator armature and housing can be joined the front end housing of various modes, can be implemented in the multiple occasion and be connected with miscellaneous equipment, be convenient to the technological transformation of used equipment and the type selecting of new equipment, range of application enlarges, and is flexible and convenient to use.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
